Intellij editor not showing what has been modified on a particular line, only showing something is modified.
已回答
The line in the code is as below,
Intellij is showing that something on this line has been modified but not showing what is modified. But when I run git diff command I am clearly able to see what is modified. Please find the attached screenshot of git diff output.
So Intellij not showing '<E2><80><8B>' in diff inside editor. Let me know what's wrong, and how to avoid such things in future.

This is because the difference is in the ZERO WIDTH SPACE symbol, and it is not displayed in the editor - see https://youtrack.jetbrains.com/issue/IDEA-115572
